As for the internal gravity distribution, this is also easy to understand.
When inside a wormhole, it's impossible for humans to enter curvature navigation; they can't wrap the mother ship in a curvature bubble. Additionally, due to the environmental issues inside the wormhole, Lu Yuanming couldn't use his acceleration to ensure the overall vector and angular vector remain unchanged.
Because of this, the mother ship and the Moon must consider the tidal forces caused by uneven gravitational distribution when traversing the wormhole.
If the changes in gravity within the wormhole are too drastic, then both the mother ship and the Moon could be torn apart into fragments by the tidal forces.
Fortunately, all these worries are gone now; this is an artificially created super-gigantic wormhole channel, a high-speed route from one end of the universe to the other.
"The concerns about the wormhole itself are gone, but what about another issue?"
